13th September 2023 Feature The landscape of sustainable aviation continues to evolve at pace, with airport ground transportation emerging as a focal point for innovation. Tom Batchelor reports Airport buses are a key component of the overall airport infrastructure and can play an important role in curbing emissions. Traditionally, buses have been synonymous with high fuel consumption, emissions and noise pollution. However, airports worldwide now recognise the urgent need to transition towards greener and more efficient transportation solutions, spurring developments in design, operation and energy sources. Electric- and hydrogen-powered vehicles are an increasingly common feature, both airside and when taking passengers to off-site car parks.
